Isn't this by design? I mean, when you're not signed at the start the options of the default user are being used.
HKEY_CURRENT_USER\Software\Patchou\MsgPlus2\DefaultConfiguration
nothing wrong in that I think (you can change it to use the "nobody"-options).

Or do you mean the beheviour when you sign out that the options of the last signed in user are still being used, instead of the default user (which can indeed be a "security" risk for POP3 passwords or so)?
